Neutrophils form neutrophil extracellular traps (NETs) of decondensed DNA and histones that trap and immobilize particulate matter and microbial pathogens like bacteria. NET aggregates reportedly surround and isolate large objects like monosodium urate crystals, which cannot be sufficiently cleared from tissues. In the setting of acute necrotizing pancreatitis, massive tissue necrosis occurs, w...

The objective of interstitial laser coagulation (ILC) of benign prostatic enlargement is to achieve a marked volume reduction and to decrease bladder outlet obstruction and lower urinary tract symptoms with minimal morbidity. Coagulation necrosis is generated well inside the adenoma by means of specifically designed laser applicators combined with either a Nd:YAG laser or a diode laser. Because...

A 32-year-old male came to the emergency room with a crescentric 4x11 cm tissue defect at the right temporo-parietal region. Brain tomography showed a tissue defect in the right parietal region but bone integrity was preserved. A free flap procedure was performed to protect the cranial bones. Two months after discharge from the hospital, he presented with a draining dirty wound that appeared ne...

Endodontic treatment of immature necrotic teeth is a real challenge. Recently, a biologically based treatment strategy, referred to as regeneration, has been introduced. Tissue regeneration requires the presence of stems cells, a scaffold, and growth factors. Endodontic regeneration may improve the prognosis of immature necrotic teeth by re-establishing the functional pulpal tissue and further ...

Labyrinthula zosterae is clearly shown to be a primary pathogen of eelgrass Zostera marina L., not merely a secondary infection of senescent leaves or an indication of decomposition. The results of this investigation using a Diving-PAM fluorometer indicate that the regions of tissue photosynthetically compromised by Labyrinthula are substantially larger than previously thought. Labyrinthula mov...

OBJECTIVE To investigate the ability of high-resolution MRI to determine composition and microanatomy of atherosclerosis in mouse aortic root and brachiocephalic artery. METHODS AND RESULTS Aortic root and brachiocephalic arteries of apolipoprotein E knockout (apoE-/-) mice fed Western diet for 10, 20, or 30 weeks were imaged ex vivo (11.7 T; 3D multiecho sequence; resolution 47x47x62.5 micro...

background: replacement of the lost tissue is the major concerns of the plastic surgeons. expanded area should be coherent with the surrounding tissue. tissue expansion technique is the reforming methods the skin tissue scarcities. several methods for tissue expansion are available; including usage of silicon balloon and injecting fluid into the tissue expander. materials and methods: in a clin...

When any tissues are injured, as is well known, necrosis may resu]t at the site of the injury in the ti$sues. Although there are many causes of necresis, we can classify them into non-infectious such as physical er chemical stimuli or insuficiency of blood supply, and infectious, due to microorganisms, The necrotic tissue seems to be not only useless but even a foreign substance for the individ...

background it has been reported that systemic administration of allopurinol improves cell survival. this study was aimed to evaluate effects of allopurinol on skin flaps in dogs. methods twenty dogs underwent one skin flap surgery with a 2-week interval. the first procedure was performed according to the standard protocols. the second phase was started by a 1-week pretreatment with allopurinol....
